1. 切换到项目位置。

2. 创建一个项目的一新分支。

mike@win10-001 MINGW64 ~/cookbook/cookbook (master)
$ git branch first-branch

3. 切换到新建的分支下。

mike@win10-001 MINGW64 ~/cookbook/cookbook (master)
$ git checkout first-branch
Switched to branch 'first-branch'

mike@win10-001 MINGW64 ~/cookbook/cookbook (first-branch)

4. 第2步和第3步可以合并成一步。

mike@win10-001 MINGW64 ~/cookbook/cookbook (first-branch)
$ git checkout -b first-branch

5. 改变文件的内容。

mike@win10-001 MINGW64 ~/cookbook/cookbook (first-branch)
$ echo "Change" >> README.md

6. 提交这个改变

$ git commit -a -m 'Readme changed'
warning: LF will be replaced by CRLF in README.md.
The file will have its original line endings in your working directory.
[first-branch dc7b6d5] Readme changed
  1 file changed, 1 insertion(+)

7. 推送分支到gitlab服务器

mike@win10-001 MINGW64 ~/cookbook/cookbook (first-branch)
$ git push -u origin first-branch

Writing objects: 100% (3/3), 262 bytes | 131.00 KiB/s, done.

  * [new branch]      first-branch -> first-branch
Branch 'first-branch' set up to track remote branch 'first-branch' from 'origin'.

8. 在Gitlab服务器查看我们推送的分支

9. 从以下图可以看到创建的分支first-branch和master分支。

10. 切换到master分支。

$ git checkout master
Switched to branch 'master'
Your branch is up to date with 'origin/master'.

11. 合并first-branch分支到master分支。

$ git merge first-branch –no-ff

12. 从第11步输出的信息可以看到，给我们一个机会去改变提交的信息。在我们保存和关闭编辑器的时候，这个分支将会合并，具体信息如下.

mike@win10-001 MINGW64 ~/cookbook/cookbook (master)
$ git merge first-branch --no-ff
Merge made by the 'recursive' strategy.
  README.md | 1 +
  1 file changed, 1 insertion(+)

13. 推送改变到Gitlab上的master.

mike@win10-001 MINGW64 ~/cookbook/cookbook (master)
$  git push origin master
Counting objects: 1, done.
Writing objects: 100% (1/1), 223 bytes | 223.00 KiB/s, done.
Total 1 (delta 0), reused 0 (delta 0)
To gitlab.aishangwei.net:root/cookbook.git
    53ec2ca..5e1ebdd  master –> master

14. 删除所创建的分支。

mike@win10-001 MINGW64 ~/cookbook/cookbook (master)
$ git push origin --delete first-branch
To gitlab.aishangwei.net:root/cookbook.git
  - [deleted]         first-branch

15. 在gitlab服务器上查看信息如下。
